What do vanadium framework sites look like in redox model silicate zeolites?

Frederik Tielens, Monica Calatayud, Stanislaw Dzwigaj, Michel Che

Ab initio periodic DFT Calculations on the structural and energy properties of different model vanadium framework sites in vanadium-substituted zeolites containing sodalite cavities are presented and related to experimental FTIR measurements on V containing SiBEA zeolite. The vanadium framework…

Exploring the reactivity of intraframework vanadium, niobium and tantalum sites in zeolitic materials using the molecular electrostatic potential

Frederik Tielens

The acid-base properties of group 5 zeolitic structures are discussed using the molecular electrostatic potential. The results point out that vanadium doped zeolites are less appropriate for electrophilic reactions, yielding minor basic character when they are compared with Nb or Ta doped zeolites…

Phosphorylation of a conserved serine in the deoxyribonucleic acid binding domain of nuclear receptors alters intracellular localization.

Kai Sun, Vedrana Montana, Karthikeyani Chellappa, Yann Brelivet, Dino Moras, Yutaka Maeda, Vladimir Parpura, Bryce M Paschal, Frances M Sladek

Nuclear receptors (NRs) are a superfamily of transcription factors whose genomic functions are known to be activated by lipophilic ligands, but little is known about how to deactivate them or how to turn on their nongenomic functions. One obvious mechanism is to alter the nuclear localization of…

Two-Dimensional Layers of Colloidal CdTe Quantum Dots: Assembly, Optical Properties, and Vibroelectronic Coupling

Thomas Noblet, Souhir Boujday, Christophe Methivier, Marie Erard, Julie Hottechamps, Bertrand Busson, Christophe Humbert

The manufacturing of silica platforms functionalized by CdTe quantum dots (QDs) of 3.4 nm diameter through (3-aminopropy)triethoxysilane (APTES) aliphatic organosilanes is performed to preserve QDs excitonic properties after their transfer from colloidal solutions to surfaces at ambient air. In…

Revealing the Band Structure of FAPI Quantum Dot Film and Its Interfaces with Electron and Hole Transport Layer Using Time Resolved Photoemission

Dylan Amelot, Prachi Rastogi, Bertille Martinez, Charlie Gréboval, Clément Livache, Francesco Andrea Bresciani, Junling Qu, Audrey Chu, Mayank Goyal, Sang-Soo Chee, Nicolas Casaretto, Xiang Zhen Xu, Christophe Méthivier, Hervé Cruguel, Abdelkarim Ouerghi, Angshuman Nag, Mathieu G Silly, Nadine Witkowski, Emmanuel Lhuillier

Lead halide perovskite nanocrystals have attracted attention in the field of nanocrystal-based light-emitting diode and solar cells, because their devices showed high performances in only a few years. Among them, CsPbI3 is a promising candidate for solar cell design in spite of a too wide band gap…

Halide Ligands to Release Strain in Cadmium Chalcogenide Nanoplatelets and Achieve High Brightness

Marion Dufour, Junling Qu, Charlie Gréboval, Christophe Méthivier, Emmanuel Lhuillier, Sandrine Ithurria

Zinc blende II-VI semiconductor nanoplatelets (NPLs) are defined at the atomic scale along the thickness of the nanoparticle and are initially capped with carboxylates on the top and bottom [001] facets. These ligands are exchanged on CdSe NPLs with halides that act as X-L-type ligands. These CdSe…

Investigation of an Allergen Adsorption on Amine- and Acid-Terminated Thiol Layers: Influence on Their Affinity to Specific Antibodies

P. Thebault, Souhir Boujday, Helene Senechal, Claire-Marie Pradier

This work describes the controlled immobilization of a recognized allergen, beta-lactoglobulin, onto gold transducers with the aim of optimizing the elaboration of a biosensor directed against allergen-produced antibodies. This protein was immobilized on both amine- and acid-terminated thiol self-…
